As described in this forum question, I have created a dynamically-sizable page footer by creating an unbound group and enabling PrintAtBottom and PrintOnEveryPage. The problem I am having now, however, is that the resizing isn't playing nicely with the text of the report in the Detail section, and on one page is hiding half a line of text with the whitespace at the top of the footer (defined as padding above the horizontal line, but removing the padding and moving the horizontal line down in the footer section creates the same effect); see attachment.
I have created the footer as belonging to an unbound group instead of creating a PageFooter section in order to enable text in the footer to wrap as necessary without requiring the footer to be enormous all the time.
